Sand mastic for sash & case windows in East Haven, Angus
Problem with your window and door surrounds in East Haven? We cut out the old, prepare the joints and apply the right sealant.
- Tired mastic found when preparing windows for paint
- Wind and rain getting in round a sash window
- Gaps round a timber door in stone or brick
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sand mastic in East Haven, done properly
Across East Haven, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We work on period & listed homes, sash and case windows and timber door frames, and the jobs we see most are mastic dropping out of the joint and gaps round a timber door in stone or brick.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
There’s a 12-month guarantee on every job, whatever its size.

Common questions in East Haven
Do you work for landlords with property near Carnoustie station?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Is sand mastic in a coastal place like East Haven any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we’ll advise.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.

What else we do in East Haven
Sand mastic in East Haven: local notes
East Haven is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you look after a building such as Carnoustie High School, its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Don’t paint over the new mastic
- Look over the window mastic once a year
- Ask a joiner to look at soft timber first
- Clear gutters so water doesn’t pour onto the windows
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours per window, depending on the condition of the joints. Outside jobs in East Haven need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Keep children and pets away from the work area
- Clear the area around the work
- Let us know about parking restrictions
